CCNA › Network Services and Security
This domain covers Cisco IOS network services and security features: DHCP, DHCP snooping, NAT/PAT, NTP, DNS, syslog, SNMP, and ACLs. Questions use drag-and-drop ordering, exhibit-based troubleshooting, and multiple-select on IPv4 versus IPv6 ACL behavior, so you must know both configuration syntax and how each feature filters or translates traffic.
